Self-Powered Flexible Blood Oxygen Monitoring System Based on a Triboelectric Nanogenerator
正文
Flexible optoelectronics based on inorganic functional components have attracted worldwide attention due to their inherent advantages. However, the power supply problem presents a significant obstacle to the commercialization of wearable optoelectronics. Triboelectric nanogenerator (TENG) technology has the potential to realize self-powered applications compared to the conventional charging technologies. Herein, a flexible self-powered blood oxygen monitoring system based on TENG was first demonstrated. The flexibility of the TENG is mainly due to the inherent properties of polydimethylsiloxane (PDMS) and the continuously undulating surface of crumpled gold (Au) and the rough surface on the electrode and PDMS effectively increased the output performance. The output voltage, output current density, and power density were 75.3 V, 7.4 μA, and 0.2 mW/cm2, respectively. By etching the sacrificial layer, we then derived a flexible blood oxygen and pulse detector without any obvious performance degradation. Powered by the TENG, the detector is mounted onto the thumbnail, from where it detects a stable photoplethysmography (PPG) signal which can be used to calculate the oxyhemoglobin saturation and pulse rate. This self-powered system provides a new way to sustainably monitor physiological parameters, which paves the way for development of wearable electronics and battery-free systems.

信息更新：

美国总工厂生产的0.5KG原始包装的PDMS延期至2021年9月16日后才能交货，默认我们将发国内库存的进口分装产品（02085925-0.5KG）；另受制于有机硅大幅涨价潮影响，2021年9月1日后将上调销售价格，另行通知。Dow Corning=道康宁=Dow SiL=陶氏，都是同一家公司。 2021.09.01更新

美国总工厂生产的0.5KG包装的PDMS恢复正常进口，合法正规，质量金标准，欢迎订购使用。并承诺从我司购买的皆为原厂包装,100%未开封,附带技术手册,非国产灌装仿制、非分装、非仿冒外包装产品,可以放心使用。大量订购更有优惠。2021.04.01更新

备注：由于dowsil与道康宁公司合并，美国总工厂生产的PDMS，价格涨幅高达1倍之多，因针对科研用户使用，特备货规格0.5KG。如果您需要美国总工厂原厂生产的大规格包装的预定，可以与QQ 11366508联系给予报价/货期。2021.05更新
